That isn't strict.

> `sum = foldl' (+) 0`

here is another possibility with "sum" in it:

Prelude Data.Monoid> let f = getSum . mconcat . (Sum <$>)

Prelude Data.Monoid> f [1,2,3,4]

If you'd rather import a custom prelude instead of writing `sum = foldl' (+) 0` you might want to think about how dependencies affect maintaining a package.

What's the actual problem you're trying to solve?

I thought the answer would be easy to find on the internet, but I cannot find any package that features a strict version of `sum`.

Do you know if such a function is defined anywhere? (like a custom prelude for instance)

I know it is trivial to define, but I would prefer not to repeat myself (and somebody else).

Thanks!
